A JUST BLE CHAIR.

Application filed October 20, 1924, Seria1 No. 744,819,and in Canada Jui1e17, 1924.

adjustable chairs and an object of the invention is to provide a chair having an adjust-- able back and a leg rest and provided with pivoted side gates and tables, the various parts being designed to permit ofthe' device being used as a straight chair, an easy chair, a cot or a bed and permitting the user to have a conveniently located table for use when desired.

A further object is to construct the chair so that when used as a chair, the other idle parts thereof can be folded up tobe non-conspicuous and will not detract from the general appearance of the chair. Y

A further object is to construct the' adjustable chair in a simple, durable and inexpensive manner and so that the various parts :an be quickly brought to the several adjusted positions which they may have, depending on the requirements .at the time.

With the above more important objects in view the invention consists essentially in the arrangement and construction of parts hereinafter more particularly described, reference being had to the accompanying drawings in Which:

Fig. 1 is a side view of the chair, all'the adjustable parts with the exception of the back, being in their folded o'r not-in-u'se-po sitions. v

' Fig. 2 is a plan view of the chair appearing in Figure 1 with one of the gates' swung outwardly to form with the hinged leaf provided, a table at one side of the chair.

Fig. 3 is a rear view of the chair as it appears in Figurel.

In the drawings like characters of reference indicate corresponding parts in the several figures.

The chair which I have constructed is somewhat ofv the nature of thechair known as a Morris chair although there are a cons derable number of additions thereto.

The chair presents similar front and rear pairs of corner legs 1, 2, 3 and 4 and the front legs are connected in the ordinary manner by a cross bar 5, the rear legs by a cross bar 6 and the front legs to the back legs by sidebars 7 and side arms 8, the'arms 8 being at the upper ends of the legs and having their rear ends extending beyond the rear legs. Suitably spaced vertical closure slats 9 extend between the bars 7'and 8 and suitably spaced bottom slats 10 extend between the bars 5 and 6.

The above parts might be called the chair frame which frame is very similar to the frame on the usual Morris chair.

The chair back 11 which is of the usual type, is provided at the lower end with a pair of outstanding aligned pivot pins '12 and 13 and these pins'are received within verti-cally disposed similar guide slots 14 and 15' formed in the inner faces of the rear legs, the slots both having their lower ends rearwardly offset and then downturned as indicated at 16 (see Figure These pinsoperating the slots, control the position of the lower end of'the chair back. I

The upper end of the back is held'in place by similar sidepins '17 and 18 attached to the back and adapted to enter suitably positioned pairs of opposing slotted pockets 19 and 20 provided in theupper faces of the rearward extensions of the chair arms. One can obviously change the an lar position of the chair back by raisin the same to pass the pins 17 and 18 out 0 one set of pockets and into another, the lower pins 12 and 13 in the meantime sliding up and down the slots 14 and 15. A leg rest 21 is pivotally attached by a hinge 22to the front cross bar 5 the leg rest embodying front and rearcross bars 23 and 24' which are connected by slats 25 and being fitted with a head piece 26' positioned at right angles to the bar 24.

By observing particularly Figure 4, it

leg rest actuallyform the seat of the chair when the device is used purely as a chair. If it is desired to use the leg rest one lifts the back upwardly in order to permit the leg rest to swing forwardly and take an inclined position as shown in Figure 5, where it engages the floor and will obviously form a convenient support orrest for the legs and feet of the chair occupant.

The sides of the chair are provided with similarside gates 27 and 28, the side gates being pivotally connected by upper and lower hinges 29 and 30 to the outer faces of the front corner legs of the chair. Each side gate embodies a pair of legs 31 and 32, upper and lower horizontal bars 33 and 3e connecting such legs and suitably spaced vertical slats 35' extending between the latter bars. When not in use, these gates are in a folded position adjoining the sides of the chair and can be releasably held in place by suitable hooks and eyes, fastening them to the rear legs of the chair.

To each arm-8 of thechair I attach a triangular shaped drop leaf 36 which is attached by hinges 37 and 38 to the arm and which normally hangs down beneath the arm and rests against the slats 9. These leaves are provided so that one can form a side table at either side of the chair as he wishes, such being done by out swinging the gate at that side of the chair, then swinging up the leaf and fastening it in any suitable manner to the gate, such as by a hook 39 and an eye 40 provided. One of the leaves isshown in use in Figure 2.

lhe legs 32 of the gates are provided on their outer sides with stops or rests 41 and 42 and when it is desired to convert the chair into a crib, as shown in Figure 6, one swings the side gates forwardly, then raises the chair back to allow the leg rest to be swung forwardly until it comes to the horizontal position where it engages with the stops and finally adjusts the back 11 of the chair into its vertical position. lVhen this is done, the slats 10 and 21' close the bottom of the crib, the sides of the chair and the I gates close the sides of the crib, and the chair back 11 and the head piece 26 close the ends of the crib. The gates can be releasably connected to the head piece in any suitable manner, such as by hooks and eyes, (not shown) and a mattress (not shown) can be placed on the slats. V

In order to permit of the chair being adjusted to forni a bed for an adult persoml have provided the chair back with legs 43 and 4A which are hinged at 45 to the cross upper bar of the back and which are normally folded in against the slats of the chair, suflicient friction being developed at the hinged joints to maintain these legs normally in place. To convert the chair into a bed for anadult it is only necessary, after having brought the parts to their crib positions, to lift the chair back sufficiently high in order to permit the pins 17 and 18 to swing rearwardly clear of the rear ends of the arm extensions, then passthe pins 12 and 13 into the lower ends of the offset portions 16 of the slots and finally extend the legs 43 and 4A: tolengage' the .fioor and support the then rearmost vend of the chair back inwhich position it is shown in Figure 7.

The offset ends 16 of the slots permit the lower cross bar of the chair back to take position immediately to the side of the cross bar 6, of the chair,'with the result that the parts forming the bottom of the bed will all lie in the same horizontal plane.

I provide also a substantially rectangular table top 46 which is somewhat wider than the width of the chair and which is provided on the underside with opposing pairs of suit ably spaced guiding cleats 47 and 48 which cleats are adapted, when the said table top 7 is to be used, to pass to opposite sides of the chair arms. This top can be used when desired, whether the device is used as a crib or bed as it is simply put in place when wanted.

I might mention also that when one is utilizing thechair with the leg rest in working position he can swing the gates ahead 7 to close the sides of the leg rest, in which case the chair is used as a reclining bed.

I have not'consideredit necessary to go into a detailed description of all the various different positions which the device may take inorder'to satisfy the desires ofthe user, but it is believed from the explanation herein given that sufficient adjusted pothe upper edges of said frames, the lower terminals of said grooves being curved'rea'rwardly and then downwardly, a back frame interposed between the side frames and provided at its lower portion with outwardly projecting. pins engaging in said grooves,

rearward extensions carried by the upper portions of the side frames and equipped with a series'of pockets formed in the upper surfacesthereof, lateral projections carried by the upper part of the back frame adapted to be selectively engaged in said pockets to hold the back frame in different angular positions, the distance between said lateral projections andf the pins at the lower portlon of the back frame being greater than the distance from the upper terminals of 7 said grooves to the outer terminals of the rearward extensions of the side frames so that by moving the pins to the upper terminals of the grooves the lateral projections fmay be swung rearwardly to clear the rearward extensions of the side frames to there- 2. A chair equipped with side frames hav- 7 ing front and rear supporting posts and side arms extending between the supporting posts of each side frame, table leaves having edge portions thereof hinged to the lower edge portions of said side arms and adapted to normally lie flat against the side frames in depending relation to the side arms, apair of auxiliary side gates having front and rear supporting posts, the rear supporting post of each side gate being hinged to the front supporting post of one of said side frames by means permitting the side gate to swing rearwardly to lie flat against the side frame or to swing forwardly into a position of alignment with the side frame, each of said side gates being equipped with a hook engageable with an eyelet carried by one of said table leaves to support the latter in horizontal position when the side gate is disposed in a predetermined angular position with reference to the side frame.

3. A chair equipped with a frame having one end hinged to the front edge of the chair bottom and provided at the otherend with a head piece extending at right angle to the frame, said frame being swingable about the hinged connection to assume an inclined position extending downwardly and for-' wardly from the chair bottom or to assume a horizontal position directly over the chair bottom with the head piece extending down wardly toward the floor to provide a support for the attached end of the frame, side gates hinged to the sides of the frames by means permitting said side gates to lie flat against the sides of the chair or to be swung into alignment with said sides to provide forward extensions thereof, said gates being provided with front and rear supporting legs and certain of said legs having their upper portions reduced in cross-sectional area to provide supporting shoulders adapted to be engaged beneath the aforesaid head piece to support the frame attached to said headpiece in a horizontal position and substantially in the plane of the chair bottom.
